refactor: Improve file search tool descriptions and reliability

- Updates the description for the regex_search_files tool to dynamically indicate the regex syntax used based on the user's settings (ECMAScript or Rust).
- Refactors the core plugin match search to wait for the search view to load before attempting to access results, addressing a timing issue.
- Adds new settings for regexSearchBackend and matchSearchBackend in settings.test.ts to reflect the refactored backend options for file searching.
